Abdominal actinomycosis: evaluation by computed tomography

Abstract

Actinomycosis causes disease in multiple organ systems and involves the abdomen approximately 20% of the time. We report a case of a 48-yr-old woman with a large abdominal mass secondary to actinomycosis. The patient demonstrates the clinical and pathologic features of this disease, as well as the role of evaluation by barium examination and computed tomography (CT). A discussion of abdominal actinomycosis is included.
